To Give Someone A Ride, To Place Something On, To Load Something
transitive verb, ichidan verb
This word consists of kanji with hiragana attached. Because the hiragana ends with an う sound, you know this word is a verb. The kanji itself means ride so this word has to do with riding. There's another word that's similar (乗る which means to ride). This particular one is transitive, meaning there is a direct object. The action is done to someone or something. So this means to give someone a ride when it's used for people, and to place something on, or to load something when it's used for things. Use the せ as a hint. The せ is a "sail" (せ) that you use on your boat to give someone a ride. How nice of you.
のせる
The reading is kun'yomi (see that hiragana?) but that's the reading you learned with the kanji so you should be okay with this. Allow me to give you a ride to the next item to study.
